Beschreibung
Zusammenfassung:	The present invention relates to an interpenetrating polymer network (IPN) material comprising a copolymer of vinylamine-vinylformamide, and a homo- polymer or a copolymer of at least one monomer selected from acrylamide or derivatives thereof, acrylic acid or derivatives thereof, or a mixture thereof forming the IPN material together with the copolymer of vinylamine-vinyl- formamide. The present invention further relates to a process for producing the IPN material, and to use of the IPN material in paper industry. La présente invention concerne un matériau à réseau polymère interpénétrant (IPN) comprenant un copolymère de vinylamine-vinylformamide, et un homopolymère ou un copolymère d'au moins un monomère sélectionné parmi l'acrylamide ou ses dérivés, l'acide acrylique ou ses dérivés, ou un mélange de ces derniers formant le matériau IPN conjointement au copolymère de vinylamine-vinylformamide. La présente invention concerne en outre un procédé de production du matériau IPN, et l'utilisation du matériau IPN dans l'industrie papetière.
